I was wondering if Nokta sold a 5" coil for the Impact ? I did not see it on Kellyco's website. However, the little football coil in the Pro pack should work fine , but I do like the 5" coils. Thanks, GS

Thanks Tom, going to try the little coil that comes in the Pro Pack 1st. GS
I own every coil made for the Impact and I like them all for different applications. While I can use three for a lot of urban tot-lot hunting, and I do, it is one place where I have enjoyed using the 4X7½ elliptical DD coil. In 'average' sites that present us with an 'average' amount of cluttering discarded trash, the 4X7½ DD has worked fine for me. Around park picnic table areas with a lot of old pull-tabs, modern pry-tabs and the typical screw-on caps and crimp-on bottle caps that are also thrown out there, I used the 4X7½ DD and it handily tackled the debris fields I had to deal with.
Today, I usually use my 7" Concentric coil when first hunting almost any urban or rural site for Coins, Jewelry and all the neat small artifacts we can find out Relic Hunting. However, I do use the 4X7½ DD for some of the tot-lot sites I hunt where it can handily work in and around structures, and it sees others uses, too.
The 7" Concentric is also my most used Relic Hunting coil and it takes on iron nails and rusty tin without hesitation, but as wonderful as it is, all coils can show their strengths and weaknesses at times, and when I am dealing with any old site that has very densely littered nails and other ferrous trash, and since the older sites I like to hunt might also hold lost and easily masked smaller-size coins like silver Half-Dimes or the tiny silver 3¢ coin, I want all the odds to be in my favor and that's a strength of the round 5" DD coil.
I can't link you to my website forums here at Findmall, but you're welcome to drop me an e-mail ( monte@ahrps.org ) and I can direct you to a site of coil evaluations, and also discuss with you how the 5" coil came to be and is a vital part of my Impact accessory coil team. It came about thanks to theperformance results of a very challenging test I set up for Oregon Gregg, but once he posted the results it caught Dilek's attention and we had some discussions about search coil sizes, shapes, and how coil designs can behave differently based upon a detector's circuitry design and signal processing, especially in a dense iron contaminated site.
Shortly, I had a 5" DD to evaluate and it definitely met the performance challenge and is a very versatile search coil to have on-hand for times of need. Sadly, as Tom pointed out, Kellyco seems to drop the ball when it comes to providing consumers with available product. The 5" coil was announced on the Forums way back in, I believe, April. Consumers have asked for it and bought it from whatever source they could find, but even when I was checking, several times, during this past month to find detectors, coils and other things to replace what was stolen, Kellyco didn't have the 5" DD Impact coil in their inventory and thee different people I spoke to there said they didn't have it or know it was made.
I just checked, just now, and they still don't show the 5" DD for the Impact or the middle rods for the Impact, and I want to order about four or five of those rods.
Pester them if you must, but the 5" DD coil IS made and SHOULD be available to consumers.

The word is won't not want, and anyone who has followed Kellyco for decades KNOWS that they list all sorts of products they don't have in-stock. A new detector is announced and they have it shown/listed to take pre-orders. You know, "Here it comes, order it now ... EVEN THOUGH IT ISN'T EVEN OUT YET!.treasure_hunter said:
Kellyco even jumped the gun on an Impact that wasn't even designed or discussed yet once the Makro Racer was first on the market, showing a sort of gray colored version of the red colored Racer that even irritated the manufacturer, likely done to hamper sales of the Makro product, which they didn't carry at the time, so they were showing a non-existent detector to take orders and it, so don't try to spoof a bunch of us who are more in-the-know about Kellyco's antics. I've seen and dealt with them often since the latter '80s so don't try and tell us Kellyco won't list it until it is in stock.
But let's also consider when they get around to ordering inventory in the first place, especially since they are not just a Dealer but are supposed to be a Distributor for other Dealers as well here in the
and 
. If you are a big name Dealer and want to offer quality products, as in made by a detector company and not just inferior fluff added in a package-deal, then you want to also offer the available search coils for the detectors you sell. The Nokta Impact has been on-the-market almost all year and many were alert to taking preorders early this year.Then on July 28th, here on Findmall and other Forums, Dilek at Nokta Detectors, announced the new 7" Concentric search coil. Announced it to everyone so Dealers/Distributors should have immediately noted this new accessory coil and quickly stocked some into the inventory and offer it ... even if taking pre-orders before it arrived!

I just now checked the Kellyco Website, selecting Nokta manufacturer, and it had 3 pages with detectors and accessories. On Page 3 it showed the 7" Concentric and 5X9½ DD open-frame coils, but NOWHERE did I see the middle rods for the Impact [size=small](and I need to get 4 of them)[/size] nor the excellent round 5" DD coil. This coil was designed to help hunt in very dense iron contaminated sites to unmask desired smaller-size targets like US Half-Dimes, which are kind of like hammered silvers over in Europe.
I had all my extra coils and rods and 5 detectors stolen last month so I set out to re-supply my main use arsenal with replacement detectors and coils. I looked and looked, and called three times to Kellyco in search of the 5" DD for the Impact. It's not to be found!! I kindly got a replacement 5" and 7" out of Turkey, but I just checked, again, and the 5" DD isn't there on Kellyco's website. But look at this announcement:
NOKTA MAKRO COIL ASSORTMENT

Dear Valued Customers,
Due to customer feedbacks and requests, we have made some changes to the Nokta / Makro coil assortment as outlined below:
• RC26/FC26/FR26 coils have been discontinued and replaced with RC24/FC24/FC24 coils. This new 9.5’’x5’’ non-buoyant design offers convenient use under water.
• FGP24 has been added to the Fors Gold+ coil assortment.
• We have added a new 5’’ coil (IM13) to the Impact coil assortment.

JUNE 29th !! There's no need to wait for stock to arrive in inventory when it was announced almost 5 months ago! I have been using the 5" all along and those who could acquire one ... elsewhere ... also have used the 5" with success. I know a lot of consumers have e-mailed or PM'ed me and asked about it and where it is available. Again, no fewer than 3 phone calls to Kellyco over the past several months and then 3 since my 5" was in the stolen items in early October, and I was told by at least two Kellyco sale persons that there was no 5" coil for the Impact. That it wasn't in your/their 'catalog' and that they, Nokta, must not make one for the Impact.
Desired product should be stocked by a serious Dealer, and for certain by any savvy Distributor.
Product could be / should be listed and shown with a Pre-Order statement IF it isn't currently in-stock.
Distributor's should make sure they have stock ordered when their inventory is getting low to be sure to have available inventory on-hand and not run out.
My recent Impact Pro Pack came from a Turkey Dealer and was delivered to the USA in a matter of days. My replacement search coils also came out of Turkey and arrived in a matter of days. Yes, it takes time for product to arrive in Oregon from Turkey, but it shouldn't take as many DAYS to arrive in Florida from Turkey. Your post, 'treasure_hunter', seems to imply that it will take a long, long period of time and that just isn't so. It is a deceiving statement, much like a lot of things we hear out of any bogus outfit out there who we deal with or hear about from time-to-time. Hint!
If you work for Kellyco, you ought to make it a point to not mislead or deceive readers. Tell it like it is or don't post.
If you don't work for Kellyco but know important upper-level people as you have stated in the past, then take them to lunch and talk-shop with them. Point out that they are missing out on business, and that there are a lot of us out here who have been around for a while, or even are newer to the detecting hobby, who have not been or are not currently very satisfied with the lack of Kellyco personnel's product knowledge, and since Kellyco is supposed to be such a big presence in the industry they ought to have a media person assigned to keep up on Forum activity on various Forums to cast a better image of Kellyco and just call it like it is.
Oh, that would be different, for sure, but the many posts I have made the past months regarding the 5" DD coil or anyone's similar post, just make your/their presence known by saying something like:
"We apologize for our oversight and have ordered the 5" DD Impact coils and expect delivery soon. 'Thank You' for bringing this to our attention. It is now posted on our website and we are taking orders now."
Instead, weeks and months pass with more and more detector consumers getting disgusted by the lack of inventory and service by a company that is quick to list and push and sell higher-dollar detectors, but falls short on having any inventory or listing for popular and desired accessories.
I know, not my usual post response since I am a very patient person with a high level of tolerance, but as the year gets close to an end and I am very disgusted with what I am able to see and order, as are many other consumers and dealers, I don't mind letting loose and speaking my mind now and then. Well, this is now,

My 5" coil will be coming from Turkey not KellyCoGroundScanner said:
That's a great coil, one of my favs to be honest. Not too big and not so small you fell like your trying to paint a 747 with a Q-tip!
I love the little 5" OOR coil on my Racers, BUT to be honest, I like the NEL Snake coil better. It's just as, if not more, effective then the OOR with a little bit better coverage, but you cannot go wrong with either coil IMHO.
HH,

GS, there is a lot we might anticipate or expect fro a search coil based on size/shape and internal design. and it also depends on the conditions we are likely to encounter at out chosen hunt sites and hope to have in the way of success when it comes to good-target un-masking in very dense iron trash. When the years started, the 3-coil Impact Pro Pack seemed to be just a fine batch of coils to cover my typical hunt sites. It was a very wintry January and we had record-setting cold temperatures to complement the record-setting snowfall. Here in Vale, Oregon our 'average' annual snowfall totals to 12.2", and the water content from that and what rain we get in our arid high-desert region combines to 10.5" of precip water a year. There was one DAY last January when we received 12" by 10 PM that day and it was still snowing, and by daybreak the next day, 24 hours later, we had an addition 6" of snow I had shoveled during the night.
So, there I was with a wonderful Impact test unit and I did all sorts of indoor evaluations to lean all that it had to offer feature-wise, and made some drives off to the east in Idaho, or stretched them off further to visit my Mom and do a little Coin Hunting far to the west around Portland Oregon. I knew the big 14X15 coil was going to satisfy me because it is close to the 13X15 DD I had for the Nokta FORS CoRe, so a nice coil option for large-target searches. The 'standard' 7X11 DD, very similar size and shape of what I had for the original Makro Racer's 7X11 DD, would be a good coil for open areas like a beach, middle of an old large grassy park, sports field or out working a plowed field, pasture or rangeland.
Then there was the new-to-the-Nokta-line 4X7½ DD. That little elliptical coil worked quite well for me when Coin Hunting the various urban sites I could make it to, and searching for all the modern-size coins we have of various denominations, and scattered about in a typical mix of modern-day trash. You know, mainly clad Dimes, Pennies, Nickels and Quarters in picnic areas, parks, parking strips and the like were 'normal' trash is also encountered like pull-tabs, pry-tabs, foil, bottle caps, and such. That little 4X7½ DD worked well, and had a nice balance and feel, kind of like the small elliptical NEL Snake coil on other makes and models.
Back in March I thought I'd do a little testing of the detectors and coils I had and invited Oregon Gregg over with his detectors and after-market search coils because I made a test scenario I use into a very tough challenge simply by changing the sample coin. I have been using my Nail Board Performance Test since I encountered an Indian Head Penny laying in-sight on the ground and surrounded by 4 iron nails of different sizes and orientation. Sort of 'where-they-fell' type of condition in a very dense iron nail contaminated old ghost town on a hill where the school used to stand.
I used that Indian Head cent at first then started using any Indian Head or modern Zinc cent as they are the same size and have a similar conductivity. I also used those same 4 rusty iron nails and duplicated their position/orientation of the nails and penny to make my Nail Board Performance Test that I used the next few days in Prescott AX giving a college class on Recreational Metal Detecting. Since stumbling upon that 4-nail & coin test scenario on Memorial Day Weekend in late May or '94, the NBPT has been regularly used when I evaluate ANY metal detector or search coil, and many avid Relic Hunters have come to agree that it is very useful, functional test that mimics some of the challenges we have when trying to unmask a good target that is located amongst some offending iron.
Then came the really tough challenge that I welcomed Gregg over to try. With the NBPT there are 4 marked routes to sweep across the nails-coin-nails, and sweeping once from the left and once from the right makes it possible to get up to 8-out-of-8 hits on the NBPT. Also, there are two ways to compare a detector and coil which are:
1.. To just barely reject the iron nails. Just increase the Discrimination level to the point all four nails are just barely rejected.
2.. Set the Discriminate level to just barley accept all four iron nails.
Why the two methods? Because some detector circuitry designs provide very quick-response and fast-recovery of adjacent targets that are audibly detected [size=small](accepted)[/size], while some do not perform well when they are also dealing with a Discriminated [size=small](rejected and not heard)[/size] nearby trash target. This is especially noticeable when hunting in and amongst a lot of ferrous trash, most notably the common iron nail.
Using a US Zinc or Indian Head Penny, or even a modern clad or older silver Dime, which is slightly thinner and narrower, most smaller-size search coils can handle the four nearby nails easily and provide very decent audio 'hits' on the coin in the #1 centered position. Using an Indian Head cent the Makro Racer and Racer 2, using the 'OOR' DD and 5" DD, or the NEL Snake or round Point DD coils, and the Nokta FORS CoRe w/'OOR' DD, FORS Relic w/5" DD and Impact w/4X7½ DD, easily produced 7 or 8-out-of-8 hits. All splendid picks for Relic Hunting in dense iron debris.
There was an obvious difference with which search mode [size=small](program)[/size] was used, such as Di2 Vs Di3 where the Two-Tone audio provides the most alertable sound from the coin, better than the Three-Tone mode which still did well. Then came the real challenge of the day. Same location and conditions, same detectors and search coils, same NB in an unchanged position .... BUT ... I changed from the Penny and modern Dime we were using to a smaller, thinner, tougher-to-find coin. I used my 1836 Capped Bust Half-Dime which is half-of the weight of a silver dime, which means it in a very smaller diameter and a much-thinner thickness. Quite a challenge in the center of that #1 circle with the four nails surrounding it [size=small](and affixed to the NB so as to always have an identical position from test-to-test)[/size].
Two Makro Racer series models, the original and a '2', and a Nokta CoRe, Relic and Impact all with their different factory-produced smaller search coils, and what was the ONLY detector and coil to get 8-out-of-8 hits on the small Capped Bust Half-Dime? My FORS CoRe w/'OOR' DD coil.
What came in 2nd place in performance? My FORS Relic w/5" DD and the Racer 2 w/5" DD gave us about 7-out-of-8 hits, but one of those passes was borderline 'iffy.'
I figured the Racer or Racer 2 with the 'OOR' coil would have been at the top of the challenge like the FORS CoRe w/the same-size 'OOR' coil, but that wasn't the case. Instead, the Racer 2 w/'OOR' came in next producing about 6-out-of-8 which is what I consider to be a just barely acceptable performance for Relic Hunting in dense ferrous debris.
My Impact w/4X7½ DD elliptical coil came in last of the detectors with a factory-produced smaller search coil, only hitting on 4 or 5-out-of-8 possible chances.
Now, here is where both Gregg & I were a little surprised because both of us figured the Racer 2 w/'OOR' would have been at the top-end of the performance in this tough challenge. And I am not a big fan of after-market accessory coils, but as Tom mentioned here, the NEL Snake coil is a very good consideration, at least on some detectors, because in that testing we did, the Racer 2 w/NEL Snake out-performed the Makro 'OOR' and round 5" DD coils, giving an 8-out-of-8 performance like I got with my FORS CoRe w/'OOR' coil.
It was intended to be more of a personal entertaining experience with Gregg so he'd better understand some site challenges we face looking for those tiny-sized coins and buttons, while both of us got to see how these coils and detectors performed. Then he posted the results on my AHRPS Forums and that got an immediate response via e-mail to me from Dilek. A wonderful sign of how a top-notch detector manufacturer will monitor several Forums to keep abreast of how their product is doing and be alert of any questionable issues. She called and we had a discussion about the Impact and the 4X7½ DD coil, and I added my comments and emphasis, based upon experiences for several decades now, of how there can be differences between detector circuitry performance and search coils size and type, such as the 14 kHz Makro racer and racer 2 and the 15 kHz Nokta FORS CoRe using the exact same size, shape and type of coil.
I pointed out how, for whatever reason, the NEL Snake coil worked well but a similar elliptical DD of close to the same size on the Impact didn't fare well. The coil worked fine for 'average' conditions on 'typical' coins we usually encounter in 'common' day-to-day Coin Hunting applications, but this was a very challenging test that was made much more difficult by using the smaller, thinner Half-Dime. Nokta Detectors has had a NBPT since I sent them one back in 2015 so they can compare targets, but as Dilek told me, they didn't have a tiny Half-Dime. Anyway, I had a good discussion with Dilek. I encouraged them to consider making a small 'OOR' or 5" DD coil for the Impact as I felt it would work better on such a tough test, and I also stressed, once again and as often as I could, that I wished there was a smaller-size round Concentric coil for their Nokta and Makro detectors, too.
A tip-of-the-hat went to Nokta as they didn't waste any time working on a new smaller coil for the Impact. There was a Forum Post on April 5th that read:

Hello Monte!! Regarding this subject - A small round coil for the Impact has been developed for your nailboard testing and it will be on its way to you soon.
I got an e-mail and a call for a heads-up that they made two 5" DD coils, one for me to evaluate and one to have in-house with the engineers, and to give it the same comparison test. It soon arrived and I tested it then called Oregon Gregg to come on over to witness the performance, and again we duplicated our efforts. The round 5" DD on the Impact worked great on the NBPT with the 1836 Capped Bust Half-Dime, and basically matched the performance of the Relic and Racer 2 with their 5" DD coils. I let Dilek know and soon the 5" DD was in production and announced for the Impact.
Is the small elliptical DD coil a good coil? Yes, it is, and I have one in my arsenal that I use during winter months for Coin Hunting as a complement to my trusty 7" concentric coil that gets used the most of all the coils. During the 8 or 9 months when I spend most of my time Relic Hunting older, ferrous littered sites, I use the 7" Concentric and 5" DD coils the most, to be sure.
Coil choice depends a lot of how often we get out hunting and the density of trash we are dealing with, not to mention iron-based debris combined with higher-conductive modern junk. With the Impact's versatility, it is the ONLY detector model in my personal arsenal that I own every search coil for that Nokta makes for it. Each coil has it's strengths and weaknesses so pick the one you feel will serve your needs the best.

So, there I was with a wonderful Impact test unit and I did all sorts of indoor evaluations to lean all that it had to offer feature-wise, and made some drives off to the east in Idaho, or stretched them off further to visit my Mom and do a little Coin Hunting far to the west around Portland Oregon. I knew the big 14X15 coil was going to satisfy me because it is close to the 13X15 DD I had for the Nokta FORS CoRe, so a nice coil option for large-target searches. The 'standard' 7X11 DD, very similar size and shape of what I had for the original Makro Racer's 7X11 DD, would be a good coil for open areas like a beach, middle of an old large grassy park, sports field or out working a plowed field, pasture or rangeland.
Then there was the new-to-the-Nokta-line 4X7½ DD. That little elliptical coil worked quite well for me when Coin Hunting the various urban sites I could make it to, and searching for all the modern-size coins we have of various denominations, and scattered about in a typical mix of modern-day trash. You know, mainly clad Dimes, Pennies, Nickels and Quarters in picnic areas, parks, parking strips and the like were 'normal' trash is also encountered like pull-tabs, pry-tabs, foil, bottle caps, and such. That little 4X7½ DD worked well, and had a nice balance and feel, kind of like the small elliptical NEL Snake coil on other makes and models.
Back in March I thought I'd do a little testing of the detectors and coils I had and invited Oregon Gregg over with his detectors and after-market search coils because I made a test scenario I use into a very tough challenge simply by changing the sample coin. I have been using my Nail Board Performance Test since I encountered an Indian Head Penny laying in-sight on the ground and surrounded by 4 iron nails of different sizes and orientation. Sort of 'where-they-fell' type of condition in a very dense iron nail contaminated old ghost town on a hill where the school used to stand.
I used that Indian Head cent at first then started using any Indian Head or modern Zinc cent as they are the same size and have a similar conductivity. I also used those same 4 rusty iron nails and duplicated their position/orientation of the nails and penny to make my Nail Board Performance Test that I used the next few days in Prescott AX giving a college class on Recreational Metal Detecting. Since stumbling upon that 4-nail & coin test scenario on Memorial Day Weekend in late May or '94, the NBPT has been regularly used when I evaluate ANY metal detector or search coil, and many avid Relic Hunters have come to agree that it is very useful, functional test that mimics some of the challenges we have when trying to unmask a good target that is located amongst some offending iron.
Then came the really tough challenge that I welcomed Gregg over to try. With the NBPT there are 4 marked routes to sweep across the nails-coin-nails, and sweeping once from the left and once from the right makes it possible to get up to 8-out-of-8 hits on the NBPT. Also, there are two ways to compare a detector and coil which are:
1.. To just barely reject the iron nails. Just increase the Discrimination level to the point all four nails are just barely rejected.
2.. Set the Discriminate level to just barley accept all four iron nails.
Why the two methods? Because some detector circuitry designs provide very quick-response and fast-recovery of adjacent targets that are audibly detected [size=small](accepted)[/size], while some do not perform well when they are also dealing with a Discriminated [size=small](rejected and not heard)[/size] nearby trash target. This is especially noticeable when hunting in and amongst a lot of ferrous trash, most notably the common iron nail.
Using a US Zinc or Indian Head Penny, or even a modern clad or older silver Dime, which is slightly thinner and narrower, most smaller-size search coils can handle the four nearby nails easily and provide very decent audio 'hits' on the coin in the #1 centered position. Using an Indian Head cent the Makro Racer and Racer 2, using the 'OOR' DD and 5" DD, or the NEL Snake or round Point DD coils, and the Nokta FORS CoRe w/'OOR' DD, FORS Relic w/5" DD and Impact w/4X7½ DD, easily produced 7 or 8-out-of-8 hits. All splendid picks for Relic Hunting in dense iron debris.
There was an obvious difference with which search mode [size=small](program)[/size] was used, such as Di2 Vs Di3 where the Two-Tone audio provides the most alertable sound from the coin, better than the Three-Tone mode which still did well. Then came the real challenge of the day. Same location and conditions, same detectors and search coils, same NB in an unchanged position .... BUT ...

I know I'm a little late, but I wanted to add in that after waiting 5 months for the FGP 5.5x10 concentric to be in stock and being told they were in order. I ordered from a dealer in turkey...... 3 days later, it was here.
I'm all about ordering from our home dealers, but there's only so long I could wait.
Kellyco and I have gone around more than once.
I'm not here to bash them. I did get my relic quickly after preordering it, but they seem to lack a but in accessories or seemingly knowledge of their own stock.
I remember ordering lower rods for some accessory coils and then hardware and finding out they were still shipping the very first version of the fors core hardware that won't even fit in the modern ears of their nokta coils. This was 3 months after relic release.
Ahh. I've been wanting to vent that for quite some time.
Sorry if that sounded bad and I'm not one to whine or cry about things here, but seemed fitting for the thread.
Best bet would be to actually call and speak with someone there. May not get the answers you want, but you have a better chance.

Just wondering between the 7" the 5" and the above mentioned how they compare?
There is no 'perfect detector' nor a 'perfect coil' because there are so many different search site applications and challenges for us to deal with. I hold out hope my stolen detectors will be found and recovered, but until then I also bought a replacement Impact, Relic and CoRe for those that were missing from my detector battery. The Impact and search coil assortment has been the biggest challenge for me to try and pick a favorite coil when you asked "how do they compare?"Low-Boy/LCPM said:
With my FORS CoRe it was easy. The small 'OOR' DD coil for working in and around the nastiest, densest trash I frequently encounter made it the one-and-only small-coil pick. In the mid-sized coil category, for more open areas with a low to modest amount of trash, it was the 5½X10 DD, but I honestly didn't use it all that often, and now prefer the looks, the weight, the feel and balance [size=small](in other words I like it)[/size] of the newer 5X9½ open-frame Double-D coil. Therefore, my two CoRe devices are ready to grab-and-go with an 'OOR' outfitted to one of them, and the 5X9½ open-frame on the other. In my accessory coil tote I have the standard 7X11 DD and 13X15 DD attached to lower rods so they can be mounted for 'special applications.'
My FORS Relic was a little trickier to establish a coil choice because it came with the 5" and 7X11 DD coils standard. Easy to 'compare' those two as one's for trashy sites and the other isn't. But I also had the 5½X10 Double-D as well as the 5½X10 Concentric coils. Same physical size, but different internal layout and noticeably different in-the-field performance based upon the sites I was hunting. I hunt places that have a rather 'busy' accumulation of junk to deal with, and my #1 use Relic unit sports the small 5" DD for trashier sites. My 2nd Relic is now equipped with the newer 5X9½ DD which, like with the CoRe offerings, I happen to prefer the appearance and feel of this coil and enjoy how it performs afield, making it my pick for most low-to-moderately littered and more open sites for a mid-sized coil.
The standard 7X11 DD and 5½X10 Concentric coils, each on their own lower rod, are near the top of the extra coils in my tote because that Concentric adds a little different 'dimension' to the Relic's in-the-field performance abilities. Once I get another rod-set powder-coated to match my custom appearance for the Relic and CoRe series, I'll likely mount up my 'revised prototype' Relic and the Concentric coil to also have it at-the-ready. Both the CoRe and Relic ought-to-have [size=small](in my personal opinion and agreed upon by many folks I hear from)[/size] the round-shaped 7" Concentric coil made for them as well. It might make coil selection for them more thought provoking, but in the end I am sure most would be quite pleased with that coil option in their arsenal ... or better still attached to their detector!
Not a lot of 'comparing' necessary with the CoRe and just a little with the Relic, but this brings us to the top-of-the-line Nokta Impact. This one is tougher and in some ways, for some folks, can be quite challenging to try and decide on a single coil to 'fit' a particular category, those being a 'Smaller-Size' coil, a 'Mid-Size' coil, and a 'Standard-Size' coil to fit different site conditions and challenges. For me, I ended up breaking it down more seasonally between what is my main Relic Hunting time of the year when I work dense iron debris in ghost towns, homesteads, old encampment sites, etc.; or the season when I am more confined to Urban Coin Hunting at the typical parks, schools, parking strips, private yards, and so forth.
You asked about 'comparing the 5X9½ DD with the 7" Concentric and 5" DD' coils', but you left one out of the mix. You forgot about the smaller elliptical coil, the 4X7½ DD. Impact coil picks can get confusing, too, especially based on how someone might consider the off-sized elliptical coils. For example, the Impact Pro Pack comes with the standard 7X11 DD and small 4X7½ DD. Is that more of a 4" coil, or more like a 7½" coil, some might winder? To some the 4" width might seem like it would make it as good as a round 5" DD for very trashy sites, but it doesn't. They might also think the 7½" length would provide them a lot of extra coverage, andin the long run, compared with the round 5" DD, it does, but not a lot.
Then consider the new round 7" Concentric coil. Do the 7" Concentric an the 4X7½ DD coils come out about equal in 'coverage' and 'separation' and general 'performance?' Well[size=small]l[/size][size=small]l[/size][size=x-small]l[/size][size=X-small]l[/size] ... no, they don't. A similar size front to rear, but different EMF shapes and designs and different functionality. And since the 7": and 7½" size is considered, are those 'smaller-size' search coils, or are they more of a 'mid-size coil?' That's part of the individual's perspective based upon the type of site and trash conditions they might deal with, and especially if a lot of ferrous trash is in the mix. I know some people who think an elliptical coil with a 5" or 5½" or 6" width is still, a 'smaller=size' coil, even if the elliptical's length is 8", 9", 9½" or 10" .... but I don't.
Here is how I considered the available coils for the Impact in my arsenal. For the ugliest, most challenging dense iron trash sites, the round 5" DD is THE coil to have and use. For me, after using a very tough challenge after the Impact was in my hands, and all the coils available for it failed to perform well, including the 4X7½ DD, Nokta sent me a 5" DD to evaluate. It improved the performance immensely, bringing it up on-par with the Relic with its 5" DD coil and close to the CoRe w/'OOR' DD, so I keep the 5" DD mounted during my Relic Hunting 'season' for nasty sites.
For me, it was the better of the two smallest overall sized coils to use. Now, to the 'mid-sized' search coils for the Impact, and there I have both of them, one mounted full-time and the other for other times I want to use it. The new open-frame 5X9½ DD has worked great for me in open areas with a limited amount of trash and it's also on a spare lower rod for quick-change afield, and it is the coil I like to have mounted to a 2nd Impact, especially during Coin Hunting season, to replace the 5" DD I prefer for Relic Hunting season.
But the round 7" Concentric coil happens to be just about ideal for me as a full-time, permanently-mounted coil on my #1 use Impact, for both Coin Hunting and Relic Hunting applications. And because it is a Concentric design, I get much more tell-tale visual and audio Target ID in places with a lot of iron discards, or especially small shards of rusty tin. It is an excellent mid-size coil that still provides functional depth of detection while doing well when it comes to handling debris-filled sites. And it 'classifies' rusty tin, steel washers and most similar ferrous trash better than a DD design, assigning it a lower and more working numeric VDI reference than the high 'dime' or 'quarter' read-outs we get all too frequently with a DD of any configuration or size.
So, we all are going to have our favorite types or sizes of coils, thus we'll 'compare' them differently, but these are my personal 'comparisons' of them. The round 7" Concentric is just about the idea size, shape and type [size=small](Concentric)[/size] that I want mounted most often for most sites I hunt. Then either the round 5" DD will be working in really dense iron when Relic Hunting, or the 5X9½ DD for more open area, lower-targets sites for Coin Hunting as well as Relic Hunting.
Sorry this is a long rambling reply, but what did you expect from me?
In a way it is difficult to describe how and why I 'compare' these coils unless it is to someone who has had the opportunity to use them all in a variety of sites. Of course if someone had, they could answer their own question. 
Have a Great Christmas and Holiday Season and may spring arrive early for all of us.

Great response as always. I have the 7" and should have taken it to this site yesterday but instead used the 9.5 X 5 and had a hard time in iron with it. Of course now I want the 5 and the seven to take on hunts but can't find the 5 for sale anywhere. So I will keep an eye for it and hope that is comes out for sale this winter when I do most of my hunting. Great info thanks again...
Just finished shoveling snow this evening, preparing for s freshly whitened Christmas Day, and figured I take on a few Forum posts and e-mails before I set some cookies and milk out for Santa and grab a winter's nap. A dark, still night with a light falling snow, and in the peace and quiet I can only think of one thing right now ... 
As for Christmas Day we are only 122 days away from the start of our 7th WTHO and I am more than eager to get up to the mining era ghost towns we plan to search, and I'm comforted knowing that every detector in my Regular-Use 'Team' is ready, and very capable, to take on the rusty tin and other debris that challenges us there.
Plus we have folks come from several states for these WTHO's and it's always interesting to see what detector and coils they are using, listen to their comments and questions, and get to see all the results from our efforts. Several travel up from California for our open to anyone Outings, and there are three base locations for three WTHO's this year, here in Eastern Oregon then two in Nevada. Warm thoughts for a cold winter's night.
When there is a bigger mix of trash, including nails, other iron and non-iron junk, and rusty tin,
then I'll be working the 7" Concentric, or the 5" DD if it is really ugly with dense debris, and using the Di-3/Three-Tone mode that has been serving me well in such sites or three years now on all my Nokta devices. I sure wish the 7" Concentric coil was made for the CoRe and Relic units, but for now I only get to enjoy it on the Impact.
When they knew that they quickly put the 5" DD into production for the Impact, announced it on many Forums, but the problem here in the USA is the 'Distributor' who, for some dumb reasons, hasn't seen fit to stock this excellent small coil. Everyone ought to get on Kellyco's case about not having the 5" DD, and other desired things, in-stock and available and advertised on the website. I know several people who went through a Dealer in Turkey they found on the big 'bay' site to get one. Pester Kellyco after the Holiday and let them know it should be in stock.
Search coil selection can be interesting and remember it isn't just about the coil's size or shape or design. There is a blend of behavior associated with the particular detector's circuitry design and performance, too. I have used Double-D coils since they were first brought to the hobby detectors in '71 by Compass with their straight TR models, and to this day I enjoy some Double-D coils on some makes and models of detectors, but I also favor a good Concentric coil on select detectors as well and prefer them on those models to a DD design most of the time.
My current three Tesoro units all have 6" or 7" Concentric coils mounted for regular use, and the only Double-D I have is a larger-size 8X11 for the Vaquero. I also keep a 6½ Inch Concentric on my main-use White's MX-7, but do have a Detech 7" DD mounted on my other MX-7. My smaller and medium size coils, the 'OOR' and 5X9½ DD's are fitted to my two FORS CoRe's, and my two Relic devices sport the 5" DD and 5X9½ DD coils. However, I do have at-the-ready a 5½X10 Concentric for the Relic on a spare lower rod, and there are a number of places where I enjoy using it over the other two that see the most Relic model use.
But as mentioned, there isn't a comparable Concentric for my Relic or CoRe, so the Impact I grab most often keeps the 7" Concentric coil mounted, and after using that coil on the Impact when I first got it, for both Coin Hunting and Relic Hunting applications, I was totally impressed with it and didn't hesitate to make it my preferred, main-use coil for the Impact. I also really enjoy both the 5X9½ DD and smaller 5" DD on my Impact for different site challenges or field use, but they are both kind of tied for 2nd place behind the 7" Concentric coil.
It never hurts to have all three in your arsenal to add versatility to the Impact, especially since that model offers so many search modes and adjustment functions and operating frequencies that can make the different coils even more versatile. I'm glad my Regular-Use Detector Team includes this detector and 3-coil package.

Nothing wrong with the 5X9½ DD and I enjoy using it in lower level trashy sites, and like to work that coil in sites with iron nails as a main junk-target challenge when using the Di-2/Two-Tone search mode and a comfortably slow and methodical sweep to cover the area.Low-Boy/LCPM said:
When there is a bigger mix of trash, including nails, other iron and non-iron junk, and rusty tin,
then I'll be working the 7" Concentric, or the 5" DD if it is really ugly with dense debris, and using the Di-3/Three-Tone mode that has been serving me well in such sites or three years now on all my Nokta devices. I sure wish the 7" Concentric coil was made for the CoRe and Relic units, but for now I only get to enjoy it on the Impact.The 5" DD was a terrific coil for hunting in some very bad iron infested ghost towns with the Impact, easily out-performing the 4X7½ DD that came with the Impact Pro Pack. That's a very good coil for a lot of urban Coin Hunting and such, but in a really tough challenge I did last March for Oregon Gregg, it paled in comparison with other coils on the Racer and Racer 2, Relic and CoRe. Dilek saw the posted results and contacted me about it, and as I explained, it was not the Impact's design behavior, but the coil size and shape. Quickly they designed the 5" DD and that bought the performance up to be on-par with the Relic using it's 5" DD coil, and almost to match the CoRe with the small 'OOR ' DD coil.Low-Boy/LCPM said:
When they knew that they quickly put the 5" DD into production for the Impact, announced it on many Forums, but the problem here in the USA is the 'Distributor' who, for some dumb reasons, hasn't seen fit to stock this excellent small coil. Everyone ought to get on Kellyco's case about not having the 5" DD, and other desired things, in-stock and available and advertised on the website. I know several people who went through a Dealer in Turkey they found on the big 'bay' site to get one. Pester Kellyco after the Holiday and let them know it should be in stock.
Search coil selection can be interesting and remember it isn't just about the coil's size or shape or design. There is a blend of behavior associated with the particular detector's circuitry design and performance, too. I have used Double-D coils since they were first brought to the hobby detectors in '71 by Compass with their straight TR models, and to this day I enjoy some Double-D coils on some makes and models of detectors, but I also favor a good Concentric coil on select detectors as well and prefer them on those models to a DD design most of the time.
My current three Tesoro units all have 6" or 7" Concentric coils mounted for regular use, and the only Double-D I have is a larger-size 8X11 for the Vaquero. I also keep a 6½ Inch Concentric on my main-use White's MX-7, but do have a Detech 7" DD mounted on my other MX-7. My smaller and medium size coils, the 'OOR' and 5X9½ DD's are fitted to my two FORS CoRe's, and my two Relic devices sport the 5" DD and 5X9½ DD coils. However, I do have at-the-ready a 5½X10 Concentric for the Relic on a spare lower rod, and there are a number of places where I enjoy using it over the other two that see the most Relic model use.
But as mentioned, there isn't a comparable Concentric for my Relic or CoRe, so the Impact I grab most often keeps the 7" Concentric coil mounted, and after using that coil on the Impact when I first got it, for both Coin Hunting and Relic Hunting applications, I was totally impressed with it and didn't hesitate to make it my preferred, main-use coil for the Impact.
I also really enjoy both the 5X9½ DD and smaller 5" DD on my Impact for different site challenges or field use, but they are both kind of tied for 2nd place behind the 7" Concentric coil.It never hurts to have all three in your arsenal to add versatility to the Impact, especially since that model offers so many search modes and adjustment functions and operating frequencies that can make the different coils even more versatile. I'm glad my Regular-Use Detector Team includes this detector and 3-coil package.
